To all whom it may concern:

Be it known that PETER J. DOCKRAY, .deceased, late a citizen of the United States, residing at WVoonsocket, in the county of Providence and State of Rhode Island, invented certain new and useful Improvements in Stop-Motions for Combers and the like, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to stop-motion for use in associationwith combers and other fiber-treating machines, and it is an object of the invention to provide elficient and reliably-acting means, the functioning of which is dependent upon occurrence of certain conditions in the material passing through the machine, for stopping the machine.

More particularly, the invention pertains to means, operating upon the choking of the trumpet through which sliver is drawn from the sliver-pan and delivered by rolls to the sliver-table, to close an electric circuit that initiates operation of mechanism that opcrates to stop the machine with which the invention is associated, as shown by. the application of said Peter J. Dockray, for stopmotion for combers and the like, filed September 5, 1914, Ser. No. 860,401, of which the present application is a division.

While it is not the intention to limit the adaptation of the invention to any particular machine for treating material while in substantially continuous movement, the invention, for purposes of explanation, is described herein as associated with a cottoncomber, in which the stop-motionfshould operate, among other times, when the material becomes choked in the trumpet or in the sliver-pan at or inv the vicinity of th entrance to the trumpet- When read in connection with the description herein, the details of construction and, arrangement of parts contemplated by the invention will be apparent from the accompanying drawings, forming a part hereof, wherein an embodiment of the invention is disclosed, for purposes of illustration.

, While the disclosures herein now are con sidered to exemplify a preferable ,embodiment of the invention, it is notthe intention to be limited necessarily thereto in interpretation of the claims, .as valterations within.

the limits of the claims can be made without departing from the nature and spirit of the invention.

Like reference-characters refer to corresponding parts in the views of the drawings, of Which- Figure'l is a plan view of a portion of a comber;

Fig. 2 is a sectional view through the sliver-pan, trumpet, and sliver-table;

Fig. 3 is a view of parts as seen'when looking in the direction of the arrow, Fig. 2; and

Fig.4 is a plan view of atrumpet and a portion of its sliver-pan.

Referring more particularly to the drawings, in which parts of a comber as hereinbefore mentioned are disclosed, 17 designates a sliver-pan into which sliver is delivered from the combing mechanism of the machine and whence it is drawn as a round strand through a trumpet 18 by an upper calender-roll 19 on a shaft 20 and a lower calender-roll 21on a shaft 22 and delivered onto a sliver-table 23, one set of such parts being shown as exemplary of others in the machine.

Extending along the sliver-table and sup ported on and insulated from the machineframe are a series of standards 24, which carry at their upper ends a rod 25 extending longitudinally of the table above the sets of calender-rolls. Fast on the rod above each set of calender-rolls is a hanger or depending support 26, from the lower portion of which laterally extends a counterrod 27 having disposition substantially parallel to the rod 25. An abutment 28 is held adjustably on the counter-rod near its free'end by a set-screw 29, and depending from the abutment is a stop 30. The abutment holds on the counter-rod a boxing31, which is a part of a swing-frame that comprises side arms 32, which flare outwardly from the boxing, as shown at 33, and then continue in parallel relation toeach other to their free ends. One of. the flaring'portions 33 of the frame is capable of contact with the stop 30, whereby downward movement of the free'ends of'the arms is limited and contact of anypart of the swing-frame with the sliver-table is prevented. The'side arms are a sufficient distance apart to enable them to straddle or to be disposed one tend frombehind and under the shaft of' I 4 plate is cut :awaytfrom its-lower edge,

i an'end of that roll. The relative disposition slightly beyond each end of the top calender-roll, and they are so curved that they exthat roll with their free ends above the sliver-table beyond the place of emergence of sliver from between the two rolls. 'One of the side arms near its "free end has'se- "curedthereto or formed integrally therewith a depending plate 34:, which extends partially across the space between-the two arms and fully across the path of movement of the sliver from betweennthe rolls. The

whereby there is formed an opening orpassageway 35 for 'movement therethrough under normal conditions of sliver from the rolls to the table. A rock-shaft or its equivalent36 is mounted pivotallynear the ends of the arms and outside of and=adjacent tothe plate e, and from this shaft depends a sliverrcontact plate or member 37 of non-conductive -material arranged to trail on the moving sliver-L. Apawl 38 also extends from the rock-shaft in such direc- 'tion. that it is: capable of engagement with 'a ratchet-wheel 39 loose on the shaft 20 of the,'uppercalendeinroll and adjacent to of the parts is such that, when the plate 37 has sliver thereunder, the pawl is kept out of engagement with the ratchet-wheel, and

that, von running out :of the: sliver' and a consequent assumption of a lower position by the plate, the pawl will engage the ratchet-wheel, close an electric circuit, .and

I stop the machine in a mannerhereinafter '18 but normally do: not contact therewith.-

between the rolls and theyplate 3,4 and by pushing againstthe plate-as it is de livered from the rolls it will operate to raise the swing-arms-to contact with the. 'upper calender-roll shaftQO .and thereby close-the electric: circuit; or such lifting of the free .end of the swingefr-ame may be such as to permit the plate 3:7 to swing sufliciently'to, bringthe pawl 3.8 into-engagement with the ratchetrwheel .39 and close It is immaterial whether the r he. circuit. circuit is closed by either orboth ofth method The-upper'end of a member 4-0'is secured to the rod 25. above the" counter-rod 27, and
